Secure computing device using different central processing resources

ABSTRACT

A computing device includes central processing resources, memory, a network interface, and a security control module. The security control module determines when to change operation of a program of the computing device. When the operation of the program is to be changed, the security control module identifies a first processing resource of the central processing resources that is currently assigned to execute the program and selects a second processing resource of the central processing resources for subsequent execution the program. The security control module then ascertains first execution settings of the program as used by the first processing resource and facilitates conversion of the first execution settings into second execution settings for the second processing resource. The security control module then de-assigns the first processing resource from executing the program and assigns the second processing resource to execute the program.

BACKGROUND OF THE INVENTION Technical Field of the Invention

This invention relates generally to computer networks and moreparticularly to security of the network and/or components thereof.

Description of Related Art

FIG. 1 illustrates a computer network that includes servers, userdevices, a local area network (LAN), a modem, one or more networks,trusted hosts, untrusted hosts, and unknown hosts. The LAN and/or themodem include a firewall. Each server and user device includes a networkinterface, network security module, memory, a central processing unit(CPU), a controller, a user security module, a user interface, an adminsecurity module, and an admin interface. The controller control user,administrator, and/or peripheral component input and output requests toaccess the memory, the CPU, and/or the network interface.

Each of the firewall, the network security module, the user securitymodule, and the admin security module functions to protect the server oruser device from malicious software attacks. Malicious software may comein the form of a virus, a worm, a backdoor, a root kit, and/or a Trojanhorse; each of which has different versions with somewhat differentpurposes. In general, the purpose of malicious software is one or moreof deleting files (user and/or system), changing files, changing diskformatting, damaging disks, slowing down the system, disablingcomputers, disabling network connections, installing backdoors and/orspyware to extract sensitive data, and/or spreading to other computersand servers.

Today, most malicious software detection techniques (e.g., antivirussoftware) are capable of detecting and preventing low to moderatesophistication attacks. Highly sophisticated attacks, however, are muchmore difficult to detect and prevent, which use techniques to blurtechnical distinctions between viruses, worms, and Trojan horses. Suchhighly sophisticated attacks are expense to develop and deploy; as such,they are typically funded by organizations that have unscrupulousintentions for large-scale computer network service disruption,extraction of a large amount of sensitive data, and/or extraction ofhighly sensitive data. Due to the intentions of highly sophisticatedattacks, the targets of such attacks are typically banks, researchorganizations, security agencies and/or firms, etc.

FIGS. 2-8 illustrate an example of highly sophisticated malicioussoftware attacking a prior art computer, which is representative ofattacking a multitude of computers concurrently, sequentially, orexponentially. As shown in FIG. 2, the malicious software (SW)circumvents the malicious software detection techniques of the firewall,the network security module, the user security module, and the adminsecurity module. This may occur as a result of a breach in networksecurity, a breach in user security, unknowingly downloading a file,opening an email attachment, tricking antivirus software into passingthe malicious software as a valid file, tricking network access securityinto believe the malicious software is a valid access, etc.

FIG. 3 illustrates the malicious SW establishing a beachhead with thecomputer (i.e., is stored in memory). Once the beachhead is established,the goal of the malicious software is to learn the hardware and softwarestructures of the computer and vulnerabilities between the hardware andsoftware interaction. The hardware structure includes memory (mainmemory and external memory), a central processing unit (CPU), networkconnections & devices, user input and output connections & devices,peripheral connections & devices, memory controller, input/output (TO)controller, etc. The software structure includes user applications,system applications, user data (e.g., files, address books, email,etc.), system data (e.g., buffers, stack pointers, physical memorymapping of data and program storage, virtual to physical memory mapping,routing tables, etc.), operating system (OS), BIOS (basic input outputsystem), user security data (e.g., credit card information, bankinginformation, passwords, user names, login information, etc.), systemsecurity data (e.g., encryption keys, key chains, etc.), etc.

At this stage of the malicious software attack, the hardware andsoftware structures each appear as white space to the malicioussoftware, which is shown in both of FIGS. 3 and 4. As such, themalicious software, from its beachhead position, monitors data flowbetween the hardware components to begin to map out the hardware andsoftware structures, to learn the hardware software interactionvulnerabilities, to learn the security measures in place, and toincrease its security level within the computer or server.

FIGS. 5 and 6 illustrate the malicious software learning the hardwarestructure, the software structure, learning the hardware softwareinteraction vulnerabilities, the security measures, and increasing itssecurity access within the computer or server. During the learningphase, the malicious software may use a backdoor to communicate itsfindings to the architect of the malicious software, which may furtherprocess the extracted data to determine the structures and/or toincrease security access. The learning process typically takes weeks tomonths to learn enough about the structure and to increase securityaccess before the malicious software can exploit the computer or server.

FIGS. 7 and 8 illustrate the malicious software exploiting the computeror server. At this stage, the malicious software has learned thehardware and software structures, their vulnerabilities, and hasestablished itself as a high priority application of the computer orserver; while being invisible to the user, system admin, and/orantivirus software. With this level of knowledge and security, themalicious software can extract whatever data it wants (e.g., bankaccounts, credit card account information, prototype designs, secretdata, confidential information, etc.); can alter or destroy any dataand/or applications it wants; corrupt and data and/or applications itwants; and disrupt or shutdown operation of the computer or server.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 9 is a schematic block diagram of an embodiment of a multiple usercomputer network 10 that includes one or more networks 12 (e.g.,Internet, wide area networks, cellular networks, telephonic networks,etc.), local networks 14-16, one or more trusted network computingdevice 18, a plurality of servers 20, a plurality of computing devices24, trusted hosts 26 (e.g., has a signed certificate, is known to userof a device, etc.), unknown hosts 28, a code generation device 32, amalicious entity 33, which places malicious software (SW) 34 into thenetwork 12. Each the local networks 14-16 includes one or more of: oneor more servers 20, a system admin device 30, one or more computingdevices 24, and a network interface 22.

The computing devices 24 (e.g., personal computers, laptop computers,cellular telephones, tablet computers, etc.) and servers 20 areprotected against the malicious software by routinely changing itssoftware and/or how it processes the software. For example, by changingan application (e.g., user application, system application, operatingsystem), or portion thereof, at a rate that is significantly less thanthe time it takes malicious software to learn the hardware and/orsoftware structures (e.g., once a day, once a week, bi-monthly, monthly,etc.), the learning the malicious software has done prior to the changeis meaningless. As another example, the computing device 24 and server20 has access to a library of multiple versions of applications e.g.,user application, system application, operating system), or portionsthereof, and routinely selects a different version of an application, orportion thereof, which renders the learning of the malicious softwareprior to the change meaningless.

As yet another example, the computing device 24 and server 20 includes aplurality of central processing resources (e.g., one or more processingmodules, one or more memory control units, one or more input/outputinterface control units, one or more peripheral control units, one ormore video graphics processing units, additional main memory, and/oradditional external memory) and routinely changes which processingresource processes which application, or portion thereof, which rendersthe learning of the malicious software prior to the change meaningless.

The changing of the application, or portion, can be done for eachapplication stored in memory or used by the computing device or serversuch that, in a given time frame (e.g., a day, a week, etc.) thesoftware stored on, or used by, the computing device 24 or server 20 ischanged. Similarly, changing of the processing resources can be done foreach application stored on or used by the computing device 24 or server20.

Routinely changing an application, or portion thereof, and/or selectingdifferent versions of an application, or portions thereof, rests, atleast in part, on the ability to generate new versions and/or multipleversions of an application, or portions thereof, quickly and reliably.UniqueSoft, Inc. has developed one or more software creation tools thatare capable of generating new versions and/or multiple versions of anapplication, or portions thereof, quickly and reliably. Such softwarecreation tool(s) are described in co-pending patent applicationentitled, “SYSTEM AND METHOD FOR GENERATING APPLICATION CODE”, having afiling date of Aug. 30, 2011, an application Ser. No. 13/221,595, nowU.S. Pat. No. 8,972,928. The co-pending patent application isincorporated in this application its entirety by reference.

FIG. 10 is a schematic block diagram of an embodiment of computingdevice 24 that includes a central processing resource 40, memory 42, anetwork interface 44, and a security control module 46. Note that thecomputing device 24 may be a processing core of the server 20, of thecode generation module 32, and/or of the trusted network computingdevice 18. The computing device 24 includes malicious software detectionprograms, which may miss highly sophisticated malicious software 34. Ifthis occurs, the malicious software attempts to establish a beachheadand then begins learning the software structure, hardware structure,vulnerabilities, etc.

In an example, the security control module 46 determines when to changeat least a portion of a program (e.g., an application, an OS, etc.) ofthe computing device 24. When the program, or portion thereof, is to bechanged, the security control module 46 sends a request to a softwaregeneration module (e.g., code generation device 32, a code generationmodule, or trusted network computing device 18) for a new version of theprogram, or portion thereof. The security control module 46 thenfacilitates receiving the new version of the program, or portionthereof. The security module 46 then facilitates replacing, within thememory, the program, or portion thereof, with the new version of theprogram, or portion thereof. The next time the program is accessed, thecentral processing resource uses the new version of the program, orportion thereof, which changes internal operation of the computingdevice thereby reducing adverse impact of malicious software (e.g.,learning the computing device and/or extracting unauthorized learneddata).

In another example, the security control module 46 determines when tochange a program (e.g., an application, an OS, etc.) of the computingdevice 24. When the program is to be changed, the security controlmodule 46, accesses a library of programs (e.g., applications, OS, etc.)that includes a plurality of versions of the program, or portionsthereof. The security control module 46 then functions to select one ofthe versions of the program, or portion thereof, and updates an activeprogram list to include the selected program, or portion thereof. Thenext time the program is accessed, the central processing resource usesthe selected version of the program, or portion thereof, which changesinternal operation of the computing device thereby reducing adverseimpact of the malicious software.

In yet another example, the security control module 46 determines whento change operation of a program (e.g., an application, an OS, etc.) ofthe computing device 24. When the operation of the program is to bechanged, the security control module 46 identifies a first processingresource of the plurality of central processing resources that iscurrently assigned to execute the program, or portion thereof. Thesecurity control module 46 also selects a second processing resource ofthe central processing resources for subsequent execution the program,or portion thereof. The security control module 46 then ascertains firstexecution settings of the program as used by the first processingresource and facilitates conversion of them into second executionsettings for use by the second processing resource. The security controlmodule 46 then de-assigns the first processing resource from executingthe program, or portion thereof, and assigns the second processingresource to execute the program, or portion thereof.

In a further example, the security control module 46 determines when tochange operation of a program (e.g., an application, an OS, etc.) of thecomputing device 24. When the operation of the program is to be changed,the security control module 46 determines whether to change the program,or portion thereof and whether to change processing resources currentlyassigned to execute the program, or portion thereof. When both theprogram, or portion thereof, and the processing resource are to bechanged, the security control module 46 facilitates a change of theprogram, or portion thereof, to produce a changed program, or portionthereof. The security control module 46 then selects a second processingresource to execute the changed program and ascertains first executionsettings of the program as currently used by a first processing resourcefor executing the program. The security control module 46 thenfacilitates conversion of the first execution settings into secondexecution settings for the second processing resource. The securitycontrol module 46 then de-assigns the first processing resource fromexecuting the program, or portion thereof, and assigns the secondprocessing resource to execute the changed program, or portion thereof.

FIG. 11 is a schematic block diagram of an embodiment of a computingdevices memory 46 that is logically divided into a user memory space 43,a system memory space 45, and a secure memory space 47. The memory 42includes the computing device's ROM (read only memory), main memory,cache memory, secondary memory (external local memory), and/or highertiered memory (e.g., external remote memory, backup tapes, etc.).

The user memory space 43 stores user applications (e.g., user programssuch as spreadsheets, databases, word processing, video games, Internetbrowser, audio/video recording and/or playback, calendar, email, etc.),user data (e.g., various types of files, address books, logininformation, bookmarkers, application preferences, etc.), and userbuffer data (e.g., intermediate data produced by an executing program,temporary user settings, etc.). Each application may include a pluralityof application functions (e.g., a block of operational instructions (orcode), a block of code for a subroutine, etc.). Each of the applicationfunctions may be separately stored in the memory 42 (e.g., theapplication is not stored in a contiguous section of the memory).

The system memory space 45 stores one or more operating systems (OS),system applications (e.g., utility application, time/date, etc.), systembuffer data, and system data. The system buffer data includesintermediate data produced by an executing system program, temporarysystem settings, etc. The OS includes a plurality of OS functions (e.g.,kernels), such as process management, interrupts, device management,networking, memory management, file system, security, and/orinput/output (TO) management. Each OS function may include a pluralityof OS sub-functions, which includes one or more blocks of code, orblocks of subroutine code. The system data includes file systeminformation (e.g., directories, etc.), security information, memorymanagement information (e.g., memory mapping, virtual to physicaladdressing, etc.), routing tables, IO device interface information, userID (identification) information, anti virus software, and/or peripheraldevice information.

The secure memory space 47 stores secure information (e.g., informationthat the user of the computing device cannot access). Such secureinformation includes the BIOS, user security information (e.g.,encryption keys, encryption protocols, etc.), and system securityinformation.

The security control module 46 functions to make the data and/orprograms stored in the memory 42 a moving target. As such, malicioussoftware is severely limited on learning the software structure of thecomputing device.

FIG. 12 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the memory 42, the network interface 44, the security control module 46,and a ROM BIOS 70. The central processing resource 40 includes one ormore of: one or more processing modules 50, one or more memorycontrollers 52, one or more direct memory access units 54, one or moreIO controllers 56, one or more video graphics processors 58, one or moreperipheral component controllers 60, one or more IO interfacecontrollers 62, one or more input device interfaces 64, one or moreoutput device interfaces 66, and one or more peripheral interfaces 68.The memory 42 includes main memory 72, one or more external memoryinterfaces 76 80, and one or more external memories 74 78. The centralprocessing resource 40 may further include additional memory, such asadditional main memories, cache memory, program memory, etc.

In an example of operation, the processing module(s) 50 includes acontrol unit, an arithmetic and logic unit (ALU), and a co-processor.The control unit coordinates and controls a repetitive sequence offetching, decoding, and executing operational instructions of blocks ofcode. The control unit determines the operational instruction, or groupof operational instructions, that is to be performed next and fetchesthe operational instruction, or group of operational instructions, frommemory 42. The control unit decodes a retrieved operational instructionby using an instruction decoder function to decipher the funtion to beperformed and to identify the data on which the function is to beperformed. The control unit also sets up logic paths (one or data andone for the function) for performing the function on the data.

The ALU and/or the co-process executes the function on the data toproduce resulting data. The control unit coordinates storing theresulting data in an appropriate memory location in memory 42.Typically, the ALU executes mathematical and/or logic functions on thedata and the co-processor executes complex functions. The control unitmay receive some of the data on which functions are performed via the IOcontroller 56 and may output resulting data to the memory 42 via the IOcontroller 56.

To facilitate fetching, decoding, and executing operationalinstructions, the control unit includes a number of control registersthat direct specific operations within the control processing resource40. Such registers include, but are not limited to, control registers,program counter register, instruction register, general purposeregisters, accumulator registers, stack pointer registers, and indexregisters. The registers are multi-bit memory storage elements and thenumber of bits is a function of the word length of the data and/oroperational instruction buses of the central processing resource.

The control unit keeps track of where it is within a program and whatneeds to be done next. To accomplish this, the program counter registercontains the address of the next operational instruction to beprocessed, and as the control logic is sequenced by the system clock,that instruction is loaded into the instruction register. On the nextsystem clock cycle(s), the operational instruction in the instructionregister is decoded by the instruction decoder. On a subsequent systemclock cycle(s), the decoded operational instruction is executed by theALU and/or co-processor.

The general purpose registers store data of various types that might beneeded during the execution of a program, or portion thereof. Theaccumulator registers send data to the ALU and/or co-processors andstore the resulting data. The stack pointer points to a location inmemory 42 were interim address or program data is to be stored, and theindex registers are used to support address offsets (i.e., used to pointto specific regions of the memory).

In another example of operation, a user of the computing device 24enters an input via an input device (e.g., keyboard, keypad, mouse,touchscreen, etc.) to evoke a program (e.g., an application). The inputis routed via the input interface 64, the IO interface 62, and the IOcontroller 56, and the memory controller 52 to the processing module 50.The processing module 50 executes one or more operational instructionsof an OS to interpret the input and identify the program to be opened.The processing module executes additional operating instructions of theOS to open the identified program. In additional, the video graphicsprocessor 58 may be performing corresponding operational instructions toprovide a graphical representation of the program opening. To executethe program, the central processing resource 40 may function asdiscussed in the preceding example.

Typically, the central processing resource 40 is supporting concurrentexecution of multiple programs (user applications and/or systemapplications) and execution of the OS. In this instance, the processmanagement functions of the OS is used to share the central processingresource among the programs such that, to the user, it appears that theprograms are running concurrently.

FIG. 13 is a logic diagram of an example of a method of securing acomputing device 24 that begins at step 90 where the security controlmodule 46 determines to change a program, or portion thereof, forsecurity purposes (e.g., thwart effectiveness of malicious software thathas circumvented anti malicious software algorithms and entered thecomputing device). The program may be an operating system (OS) thatincludes a plurality of OS functions, a user application that includes aplurality of user application functions, or a system application thatincludes a plurality of system application functions.

The OS functions include process management, interrupts, devicemanagement, networking, memory management, file system, security, andinput/output management. Each of the OS functions may include one ormore OS function sub-routines and wherein a portion of the OS includesan OS function or an OS function sub-routine. A user applicationfunction includes one or more user application function sub-routines,where a portion of the user application includes the user applicationfunction or a user application function sub-routine. A systemapplication function includes one or more system application functionsub-routines, wherein a portion of the system application includes thesystem application function or a system application functionsub-routine.

The decision as to which program to change and/or when to change it, orportion thereof, may be done in a variety of ways. For example, thesecurity control module 46 may use a pseudo random sequence to identify,at pseudo random time intervals, the program, or portion thereof, from aplurality of programs. For instance, each interval of the pseudo randomsequence identifies a different program of the plurality of programs,where the pseudo random sequence repeats at a cycle once a day, once aweek, once a month, etc. such that each program, or portion thereof, ischanged at least once in the repeating cycle.

As another example, the security control module 46 determines to changethe program, or portion thereof, when the program has been evoked apredetermined number of time or a pseudo random number of times. Forinstance, every tenth evoking (e.g., opening, use, etc.) of the program,it, or a portion thereof, is changed. The number, whether fixed orpseudo random, the number is selected to minimize the malicioussoftware's ability to learn about the program. As yet another example,the security module 46 may receive a command from a trusted managementdevice 18 that identifies the program, or portion thereof, and when itis to be changed (e.g., now, within the next 24 hours, when it has beenevoked a number of times, etc.).

As a further example, the security control module 46 determines tochange the program, or portion thereof, when the program is operatingoutside of anticipated normal operating parameters. For instance, thesecurity control module 46 tracks a program's performancecharacteristics (e.g., speed of execution, error rate, crashing, memoryconsumption, frequency of evoking, etc.) and, when the performancecharacteristics deviate from normal levels (e.g., deviate by a fewpercent or more), the security control module 46 determines to changethe program, or portion thereof.

The method continues at step 92 where the security control module 46sends a request to a software generation module for a new version of theprogram, or portion thereof. The software generation module, which mayreside in the computing device 24, within the trusting computing device18, or within the code generation device 32, generates the new versionof the program, or portion thereof, based on the same, or similar, inputrequirements used to develop the current program, or portion thereof. Inthis manner, the function of the program, or portion thereof, will bethe same or similar, but the operational instructions of the new versionwill likely differ from the operational instructions of the currentversion, thus rendering any learning the malicious software may haveacquired of the current program will be rendered useless. The softwaregeneration module includes software creation tools are described inco-pending patent application entitled, “SYSTEM AND METHOD FORGENERATING APPLICATION CODE”, having a filing date of Aug. 30, 2011, anapplication Ser. No. 13/221,595, now U.S. Pat. No. 8,972,928.

The method continues at step 94 where the security control module 46facilitating receiving the new version of the program, or portionthereof. The facilitating includes one or more of including addressinginformation in the request to receive the new version via the networkinterface 44 or a LAN interface, receiving the new version, providinginstructions to send the new version to memory 42, etc. The facilitatingmay also include authenticating the new version of the program, orportion thereof, based on a trusted relationship with the softwaregeneration module. For instance, the security control module 46authenticates the new version by verifying a signed certificate of thetrusted source, by decrypting the new version using a public key of apublic-private key pair of the trusted source, etc.

The method continues at step 96 where the security control module 46facilitating replacing, within the memory, the program, or portionthereof, with the new version of the program, or portion thereof. Forexample, the security control module 46 facilitates writing the newversion of the program, or portion thereof, to the memory andcoordinates updating a memory mapping for the program to include the newversion of it, or a portion thereof, and to exclude the old version ofthe program, or portion thereof. For instance, the new version of theprogram, or portion thereof, is written into different memory locationsthan the old version, which further aids in the thwarting of themalicious software. The older version may be passively erased (e.g.,pointers deleted and eventually overwritten with other data oroperational instructions) or actively erased (e.g., use a shreddingprogram to remove the operational instructions of the old version).

The method continues at step 98 where, when the program is evoked, thecentral processing resource uses the new version of the program, orportion thereof, such that execution of the program is changed. Bychanging internal operation of the computing device 24 reducing adverseimpact of malicious software.

FIG. 14 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the memory 42, the network interface 44, the security control module 46,and a software generation module 100. In this embodiment, when thesecurity control module 46 determines that a program, or portion thereofis to be changed, it sends a request to the software generation module100 to generate the new version of the program, or portion thereof. Therequests a local address of the software generation module 100 and mayfurther include input requirements for the program, or portion thereof.

The software generation module 100 uses the input requirements togenerate application requirements, which the software generation moduleuses to generate the new version of the at least a portion of theprogram. The input requirements include, but are not limited to, one ormore if-then-else statements, one or more state table(s), one or moremessage sequence charts (e.g., MSC), and/or another agreed up format.The software generation module 100 includes software creation tools toconvert the input requirements into one or more blocks of code asdescribed in co-pending patent application entitled, “SYSTEM AND METHODFOR GENERATING APPLICATION CODE”, having a filing date of Aug. 30, 2011,an application Ser. No. 13/221,595, now U.S. Pat. No. 8,972,928.

FIG. 15 is a schematic block diagram of another embodiment of acomputing device 24 that includes the security code module 46, the codegeneration module 100, a plurality of changeable applications (userand/or system) (1-n), a corresponding plurality of applicationprogramming interfaces (API) 101-103, a changeable operating system (OS)107, application binary interface (ABI) 105, one or more centralprocessing resources 40, and a corresponding instruction set 109. Thesecurity control module 46 determines intervals at which one or moreapplications, or portions thereof, and/or the operating system, orportions thereof, are changed (e.g., create new versions whilemaintaining equivalent functionality). Note that the security controlmodule 46 may also initiate a change to one or more APIs and/or to theABI.

In an example of operation, the security control module 46 determines tochange the operating system 107 by periodically switching to a newcompiled version of the OS, or one or more portions thereof. Forexample, the code generation module 100 generates new versions of theOS, or portions thereof, using automated code generation techniques,such as those described in the above referenced co-pending patentapplication. In this approach, the newly compiled versions of the OS aregenerated by changing parameters in the software generation tools thatdetermine the specific instructions and instruction sequences that areused in the interior of the final compiled code. This can be donewithout changing the overall functionality of the resulting block, orblocks, of code by maintaining the same functional requirements (e.g.,input, parameters, application requirements, etc.) for the newlycompiled OS, or portion thereof.

By periodically changing the OS 107 the vulnerabilities that may existin any one version of the OS are changed, which neutralizes attacktechniques that are based on the time consuming process of identifyingand exploiting these vulnerabilities. In addition, in the event anintrusion has occurred but has not been detected—a serious threat formany of today's intrusion attacks—the OS change neutralizes any OScentric intrusion software (e.g., worms and/or viruses) that may havebeen secretly stored in the memory of the computer system.

In another example of operation, the security control module 46determines to change the applications by periodically selecting anapplication to change. For the selected application, the securitycontrol module 46 instructs the code generation module 100 to compile anew version of the selected application, or one or more portionsthereof. For example, the code generation module 100 generates newversions of the selected application, or portions thereof, usingautomated code generation techniques, such as those described in theabove referenced co-pending patent application. In this approach, thenewly compiled versions of the selected application are generated bychanging parameters in the software generation tools that determine thespecific instructions and instruction sequences that are used in theinterior of the final compiled code. This can be done without changingthe overall functionality of the resulting block, or blocks, of code bymaintaining the same functional requirements (e.g., input, parameters,application requirements, etc.) for the newly compiled application, orportion thereof.

In another example of operation, the security control module 46instructs the code generation module 100 to include one or moreoperating system functions in a newly compiled version of anapplication. In one instance, each application includes its own embeddedOS 107 such that, when the application is changed, its own OS, orportions thereof, is also changed. As such, each application includes anAPI and a version of the ABI to directly communicate with theinstruction set 109. In a specific example, the applications would shareOS functions such as process management, interrupts, memory management,device management, IO functions, networking, and/or file system. Inanother specific example, each application includes its own OS functionsfor file system and memory management, while common OS functions ofprocess management, interrupts, etc. are performed by an OS 107.

FIG. 16 is a schematic block diagram of an example of an applicationexecutable by a computing device 24. The program includes operationalinstructions 112, which include a plurality of blocks of code 114 and aplurality of subroutine blocks of code. Some of the operationalinstructions include instructions regarding data 110. For example, anoperational instruction includes a command to retrieve system data 120and/or user data 122. As another example, an operational instructionincludes a command that produces intermediate data 124 from other data110, or from scratch.

In an example of operation, an application, or program, is selected viaconventional computer means to be executed. The program may be anoperating system (OS) that includes a plurality of OS functions, a userapplication that includes a plurality of user application functions, ora system application that includes a plurality of system applicationfunctions. As an example, the OS functions including process management,interrupts, device management, networking, memory management, filesystem, security, and input/output management. As another example, theuser application functions include one or more user application functionsub-routines that are dependent on the purpose of the application. Asyet another example, the system application functions include one ormore system application function sub-routines. Note that a block of codeand/or a subroutine block of code may correspond to a function, aportion of a function, and/or multiple functions of the application.

Once the program is selected, a first block of code 114-1 of operationalinstructions 112 is executed. The first block of code 114-1 may be toinitialize the program, initialize counters, initialize registers,retrieve initial data 110, etc. As the first block of code 114-1 isexecuted, one or more determinations are made as to which block of codeor subroutine block of code is to be executed next and/or whether theprocessing of the first block of code is to be interrupted to execute asubroutine block of code. For example, while executing the first blockof code 114, a determination is made to jump to subroutine block of code116-1. As subroutine block of code 116-1 is executed to perform afunction, or portion thereof, it makes one or more determinations as towhich block of code or subroutine block of code is to be executed next.As an example, the execution of the program may jump back to the firstblock of code 114-1, it may proceed to another subroutine block of code116-2 or 116-3, or it may proceeds to a second block of code 114-2. Notethat a string of subroutine blocks of code may be executed beforereturning to the main flow of program execution (e.g., executing theblocks of code 114).

At some point in the execution of the program, the execution willproceed to block of code 114-2 (e.g., via block of code 114-1,subroutine blocks of code 116-1 or 116-3). While the second block ofcode 114-2 is executing, it may generate and/or use intermediate data124, which is stored in cache and/or main memory. In addition, thesecond block of code 114-2 makes determinations as to where the programis to proceed next and/or whether the execution of the second block ofcode 114-2 should be interrupted for execution of one or more subroutineblocks of code. In this example, the second block of code 114-2 mayproceed to, or be interrupted to jump to, a fourth subroutine block ofcode 116-4. As another possibility, the second block of code 114-2 mayproceed to the third block of code 114-3 or may repeat at least aportion of the first block of code 114-1.

The execution of the operational instructions 112 of the program, orapplication, continues via block of code 114-4 and one or more ofsubroutine blocks of code 116-5 and 116-6 until it is to be closed. Atthis point, the fifth block of code 114-5 is executed to shutdown theprogram, which includes outputting updated system data 120-1 and/orupdated user data 122-1 and performing other functions to safelyshutdown or suspend the program.

When the security control module 46 identifies the program of FIG. 16for have a new version created, the entire program (e.g., all of theblocks of code 114 and all of the subroutine blocks of code 116) may begenerated as discussed above. Alternatively, one or more blocks of code114 may be selected to have a new version created and/or one or moresubroutine blocks of code 116 may be selected to have a new versioncreated. Since the functionality of the application, of a block of code,and/or of a subroutine block of code is predicated on inputrequirements, the application, block of code, and/or subroutine block ofcode may be recreated using the same input requirements and differentparameters to create a different version (e.g., includes at least onedifferent operational instruction) of the application, or portionthereof, that performs the same functions, or function. For instance,the parameters prescribe physical, logical, and/or developmentalconstraints on implementing the blocks of code 114 and/or 116. Forexample, the physical parameters may include physical limitations of thesystem (e.g., clock rates, processing rates, data transference rates,etc.) and logical parameters may include software limitations (e.g.,desired programming language, desired operating system, desired API,etc.).

FIG. 17 is a schematic block diagram of an example of storing anapplication (e.g., user application, system application, operatingsystem, etc.), or portion thereof, in memory 42 of a computing device24. The memory 42 includes a plurality of memory locations (e.g.,terabytes or more) for storing data. Per the memory management functionof the OS, different memory locations in the memory are used to storevarious data and operational instructions. For example, the system data120, the user data 122, and/or the intermediate data 124 associated withthe example program of FIG. 16 are each stored in one or more memorylocations, which may or may not be contiguous.

As is also shown, the various blocks of code 114 and the subroutineblocks of code 116 are stored in a variety of memory locationsthroughout the memory 42. If malicious software has a beachhead in thecomputing device 24, it attempts to learn the memory structure for theprogram and/or to learn the memory management function of the OS.

FIG. 18 is a schematic block diagram of an example of storing a newversion of the application of FIG. 17 in memory 42 of a computing device24. In this instance, the new version of the application, or portionsthereof, are stored in different memory locations in the memory thantheir corresponding older version. In addition, the memory managementfunction of the OS may be part of what is changed to further vary howthe new version of the application, or portions thereof, are stored inmemory 42.

The old version of the application, or portion thereof, may be passivelyerased (e.g., removed from memory map and eventually overwritten byother data or operational instructions) or actively erased (e.g.,deleting using a shredding program or the like). By storing a newversion of the application, or portions thereof, in memory in differentmemory locations (and possibly using a different version of the memorymanaging function of the OS), the learning of the application thatmalicious software may have acquired is rendered substantiallymeaningless.

While the present example has shown that the new version of theapplication, or portions thereof, are stored in different memorylocations than their corresponding older version(s), one or more of theportions of the application may overwrite its corresponding olderversion. Additional examples of storing the application or portionsthereof to circumvent malicious software's intent to learn theapplication, the software structure, and/or the hardware structure canreadily be derived from the examples presented.

FIG. 19 is a schematic block diagram of an example of obtaining a newversion 104 of an application by a computing device 24. The computingdevice 24 includes the central processing resource 40, the memory 42,the network interface 44, and the security control module 46. Thetrusted network computing device 18 includes a software generationmodule 100-1. In this embodiment, when the security control module 46determines that a program, or portion thereof is to be changed, it sendsa request 102 to the software generation module 100-1, via the networkinterface 44 and the network 12, to generate the new version of theprogram, or portion thereof. The request includes a network address ofthe software generation module 100-1 and may further include inputrequirements for the program, or portion thereof.

The software generation module 100-1 uses the input requirements togenerate application requirements, which the software generation moduleuses to generate the new version of the at least a portion of theprogram. The input requirements include, but are not limited to, one ormore if-then-else statements, one or more state table(s), one or moremessage sequence charts (e.g., MSC), and/or another agreed up format.The software generation module 100-1 includes software creation tools toconvert the input requirements into one or more blocks of code asdescribed in co-pending patent application entitled, “SYSTEM AND METHODFOR GENERATING APPLICATION CODE”, having a filing date of Aug. 30, 2011,an application Ser. No. 13/221,595, now U.S. Pat. No. 8,972,928.

Prior to sending the request and/or after receiving the new version ofthe application, or portions thereof, the security control module 46authenticates the trusted network computing device 18 (which may be anetwork host that provides code generation services). The authenticationmay be done in a variety of ways. For example, the request and asubsequent response include signed certificates. As another example, therequest and subsequent response are encrypted using public-private keypairs of the computing device 24 and the trusted network computingdevice 18. As yet another example, the security control module 46 is aregistered user of the trusted network computing device 18 and performsa login procedure to request the new version of the application, orportion thereof, and/or to receive the new version of the application,or portion thereof.

FIG. 20 is a schematic block diagram of another example of obtaining anew version 104 of an application by a computing device 24. Thecomputing device 24 includes the central processing resource 40, thememory 42, the network interface 44, and the security control module 46.The code generation device 32 includes a software generation module100-2. In this embodiment, when the security control module 46determines that a program, or portion thereof is to be changed, it sendsa request 102 to the code generation device 32, via the networkinterface 44 and the local area network, to generate the new version ofthe program, or portion thereof. The request includes a LAN address ofthe code generation device 32 and may further include input requirementsfor the program, or portion thereof.

The software generation module 100-2 uses the input requirements togenerate application requirements, which the software generation moduleuses to generate the new version of the at least a portion of theprogram. The input requirements include, but are not limited to, one ormore if-then-else statements, one or more state table(s), one or moremessage sequence charts (e.g., MSC), and/or another agreed up format.The software generation module 100-2 includes software creation tools toconvert the input requirements into one or more blocks of code asdescribed in co-pending patent application entitled, “SYSTEM AND METHODFOR GENERATING APPLICATION CODE”, having a filing date of Aug. 30, 2011,an application Ser. No. 13/221,595, now U.S. Pat. No. 8,972,928.

FIG. 21 is a logic diagram of another example of a method of securing acomputing device 24 that begins at step 130 where the software controlmodule 46 determines to change a program, or portion thereof, forsecurity purposes (e.g., thwart effectiveness of malicious software thathas circumvented anti malicious software algorithms and has entered thecomputing device). The program may be an operating system (OS) thatincludes a plurality of OS functions, a user application that includes aplurality of user application functions, or a system application thatincludes a plurality of system application functions.

The OS functions include process management, interrupts, devicemanagement, networking, memory management, file system, security, andinput/output management. Each of the OS functions may include one ormore OS function sub-routines and wherein a portion of the OS includesan OS function or an OS function sub-routine. A user applicationfunction includes one or more user application function sub-routines,where a portion of the user application includes the user applicationfunction or a user application function sub-routine. A systemapplication function includes one or more system application functionsub-routines, wherein a portion of the system application includes thesystem application function or a system application functionsub-routine.

The decision as to which program to change and/or when to change it, orportion thereof, may be done in a variety of ways. For example, thesecurity control module 46 may use a pseudo random sequence to identify,at pseudo random time intervals, the program, or portion thereof, from aplurality of programs. For instance, each interval of the pseudo randomsequence identifies a different program of the plurality of programs,where the pseudo random sequence repeats at a cycle once a day, once aweek, once a month, etc. such that each program, or portion thereof, ischanged at least once in the repeating cycle.

As another example, the security control module 46 determines to changethe program, or portion thereof, when the program has been evoked apredetermined number of time or a pseudo random number of times. Forinstance, every tenth evoking (e.g., opening, use, etc.) of the program,it, or a portion thereof, is changed. The number, whether fixed orpseudo random, the number is selected to minimize the malicioussoftware's ability to learn about the program. As yet another example,the security module 46 may receive a command from a trusted managementdevice 18 that identifies the program, or portion thereof, and when itis to be changed (e.g., now, within the next 24 hours, when it has beenevoked a number of times, etc.).

As a further example, the security control module 46 determines tochange the program, or portion thereof, when the program is operatingoutside of anticipated normal operating parameters. For instance, thesecurity control module 46 tracks a program's performancecharacteristics (e.g., speed of execution, error rate, crashing, memoryconsumption, frequency of evoking, etc.) and, when the performancecharacteristics deviate from normal levels (e.g., deviate by a fewpercent or more), the security control module 46 determines to changethe program, or portion thereof.

The method continues at step 132 where the security control module 46access a library of programs that includes a plurality of versions ofprogram when the program is to be changed and accesses the library ofprograms that includes a plurality of versions of portions of theprogram. The library of programs may be stored locally as will bediscussed in greater detail with reference to FIG. 22; the library ofprograms may be stored in a code generation module 32 of a local areanetwork; and/or stored in a trusted network computer device 18 as willbe discussed in greater detail with reference to FIG. 25.

The method continues at step 134 where the security control module 46selects a version of the program, or portion thereof, from the libraryof programs. This may be done in a variety of ways. For example, thesecurity control module 46 selects a new version of an application, orportion thereof, from a plurality of versions of application programsand using a currently active operation system program. As such, eachversion of the application is written to function on the currentoperating system. As another example, the security control module 46selects a new version of an operation system program from a plurality ofversions of operating systems. As yet another example, the securitycontrol module selects the new version of the application program fromthe plurality of versions of application programs and selects the newversion of the operating system program from the plurality of versionsof operating systems.

The method continues at step 136 where the security control module 46updates an active program list to include the selected version of theprogram, or portion thereof. The method continues at step 136 where,when the program is evoked, the central processing resource uses theselected version of the program, or portion thereof, such that executionof the program is changed, which changes internal operation of thecomputing device thereby reducing adverse impact of the malicioussoftware.

FIG. 22 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the memory 42, the network interface 44, the security control module 46,and a library of programs, or portions thereof, 140. In this embodiment,when the security control module 46 determines that a program, orportion thereof is to be changed, it accesses the library of programs140, which may stored in the memory 42 of the computing device or inother memory of the computing device not visible to the user and networkinterface 44 of the computing device 24.

The security control module 46, having identified the program, orportion thereof, and the new version of the program, or portion thereof,retrieves the new version and stores it in memory 42 as described withreference to FIG. 18. The security control module 46 may actively orpassively erase the older version of the program or portion thereof.Note that the library of programs, or portions thereof, may have alimited number of versions for each program, or portion thereof; assuch, a new version may be a previously used version, where theselection is done in a round robin manner of the limited number ofversions. Alternatively, a code generation module may continue to createnew versions of the program, or portion thereof, which are added to thelibrary to broaden the choices for selecting a new version.

FIG. 23 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the security control module 46, a library of applications 140, aplurality of APIs, a plurality of logical switches 146, a plurality ofABIs, a library of operating systems (OS) 140-1, and an instruction set109. The library of applications 140 includes multiple versions of eachapplication of a plurality of applications (e.g., 1 through napplications). For example, application 1 (e.g., a user application or asystem application) includes versions V1 through Vk and application “n”includes versions 1 through k, where k is an integer greater than orequal to 2. Further, from application to application, the number ofversions per application may be the same or different. For instance, themore sensitive the application, the more versions of the application arecreated.

Each version of an application may include a complete new version of theapplication or one or more new portions of the application.Alternatively, or in addition, the library of applications may include alibrary of versions of blocks of code of applications (e.g., a pluralityof versions of the portions of each application). In this latterexample, different combinations of versions of portions of the portionsof the application may be selected to produce a new version of theapplication.

The library of operating systems 140-1 includes a plurality of versionsof an operating system and/or a plurality of versions of portions of theoperating system. For example, the library of operating systems 140-1includes 1 through m versions of the operating system and/or 1 through mversions of portions of the operating system (e.g., process management,interrupts, device management, networking, memory management, filesystem, security, and IO functions).

The logical switches 146 may be logical constructs and/or switchingnetworks. As a logical construct, a logical switch 146 may beimplemented via software to keep track of which version of anapplication is selected and updating appropriate memory maps to accessthe selected version of the application.

In an example, one of the versions of an application is selected fromthe library 140. The logical switch 146, based on the selection 142,couples the API of the selected application to another logic switch 146that couples the selected application to an ABI. The selected OSprocesses the selected application by issuing OS operationalinstructions via another logical switch 146 to the central processingresource 40 via the instruction set. Note that several versions of theOS may be selected to support several selected versions of applications.In this instance, one or more of the selected OS's would perform theprocess management regarding use of the central processing resource 40.

In another example, from computing device to computing device, therespective security control modules select different versions ofapplications and/or different combinations of versions of applicationportions (e.g., blocks of code, subroutine blocks of code, etc.). Inthis example, each computing device functions similarly but usesdifferent versions of the applications. Thus, if a virus or worm attacksa program in one computing device, its propagation to other computingdevices and its ability to attack corresponding programs therein issubstantially reduced due to the different versions.

FIG. 24 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the security control module 46, a library of applications 140, aplurality of APIs, a plurality of logical switches 146, a plurality ofABIs, a library of operating systems (OS) 140-1, and an instruction set109. The library of applications 140 includes multiple versions of aplurality of sections for one or more applications of a plurality ofapplications (e.g., 1 through n applications). For example, application1 (e.g., a user application or a system application) includes aplurality of blocks of code, each with versions V1 through Vk. Thelibrary 140 also includes one or more applications that include aplurality of version of the application (e.g., application “n”), whichincludes versions 1 through k, where k is an integer greater than orequal to 2. The other applications of the library 140 may include aplurality of versions of the application and/or a plurality of versionsof a plurality of blocks of code of the application. Further, fromapplication to application, the number of versions per application, andnumber of versions of blocks of code, may be the same or different. Forinstance, the more sensitive the application, the more versions of theapplication, and/or versions of blocks of code, are created.

The library of OS's 140-1 includes a plurality of versions of an OS. Oneor more of the versions includes multiple versions of a plurality ofportions (e.g., functions and/or sub-functions) of the OS (e.g., blocks1-z, with versions 1-x of each block). Other versions of the OS includecomplete different versions.

In an example, if application 1 is to be changed, the security controlmodule 46 may select different versions for the various blocks. Forexample, the security control module 46 may select version 1 of block ofcode 1, version 2 for block of code 2, and so on. The next timeapplication 1 is to be changed, the security control module 46 selects anew combination of blocks of code. For example, the security controlmodule 46 may select version 4 of each of the plurality of blocks ofcode (1-z). The security control module 46 may make similar selectionsfor the various versions of the blocks of code for a version of theoperating system.

FIG. 25 is a schematic block diagram of another example of obtaining anew version of an application by a computing device 24 from a trustednetwork computing device 18. The computing device 24 includes thecentral processing resource 40, memory 42, the network interface 44, andthe security control module 46. The trusted network computing device 18includes the library of applications 140 and may further include thelibrary of OS 140-2. In this embodiment, when the security controlmodule 46 determines that a program, or portion thereof is to bechanged, it sends a selection request 142 to the trusted networkcomputing device 18, via the network interface 44 and the network 12, toreceive a different version of the program, or portion thereof, (e.g.,user application, system application, OS). The request includes anetwork address of the trusted network computing device 18 and/or of thelibrary of programs 140.

In response to the request, the trusted network computing device 18selects a version of an application or portion thereof and sends theselected version 144 back to the computing device 24. The computingdevice 24 stores the selected version 144 of the application or portionthereof as previously discussed with reference to FIGS. 17 and 18.

Prior to sending the request and/or after receiving the selected versionof the application, or portions thereof, the security control module 46authenticates the trusted network computing device 18 (which may be anetwork host that provides code generation services). The authenticationmay be done in a variety of ways. For example, the request and asubsequent response include signed certificates. As another example, therequest and subsequent response are encrypted using public-private keypairs of the computing device 24 and the trusted network computingdevice 18. As yet another example, the security control module 46 is aregistered user of the trusted network computing device 18 and performsa login procedure to request the selected version of the application, orportion thereof, and/or to receive the selected version of theapplication, or portion thereof.

FIG. 26 is a schematic block diagram of another embodiment of acomputing device 24 that includes the central processing resource 40,the security control module 46, a library of changeable applications140, a plurality of APIs, a plurality of logical switches 146, aplurality of ABIs, a library of changeable operating systems (OS) 140-1,and an instruction set 109. The library of changeable applications 140includes multiple versions of each application of a plurality ofapplications (e.g., 1 through n applications), and each version of eachapplication may be changed as discussed above. In this manner, thelibrary includes multiple versions of an application and, as time goeson, the versions are changed such that only one version of anapplication may be used for a given duration.

The library of OS's 140-1 includes a plurality of changeable versions ofan OS, or of a plurality of OSs. One or more of the versions includesmultiple versions of a plurality of portions (e.g., functions and/orsub-functions) of the OS (e.g., blocks 1-z, with versions 1-x of eachblock). Other versions of the OS include complete different versions.The versions of the OS, or portions thereof, may be changed aspreviously discussed.

FIG. 27 is a logic diagram of another example of a method of securing acomputing device 24 that begins at step 150 where the security controlmodule determines to change operation of a program, or portion thereof,of the computing device. Such a determination may be done in a varietyof ways as were discussed with reference to step 130 of FIG. 21. Whenthe operation of the program, or portion thereof, is to be changed, themethod continues at step 152 where the security control module 46identifies a first processing resource of the central processingresources that is currently assigned to execute the program, or portionthereof.

The method continues at step 154 where the security control module 46selects a second processing resource of the central processing resourcesfor subsequent execution the program, or portion thereof. For example,the first processing resource includes a first central processing unit(CPU) of a plurality of CPUs and a first operating system (OS) of theplurality of OSs and the second processing resource includes a differentone or more CPUs and a different one or more OSs. The program is a userapplication, or portion thereof, and/or a system application, or portionthereof.

The method continues at step 156 where the security control module 46ascertains (e.g., look up, special mapping built into the OS,communication with active OS, etc.) first execution settings of theprogram as used by the first processing resource. The first executionsettings includes one or more of memory management information (e.g.,where program is stored, partitioning information, segmentationinformation, paging, virtual memory map, etc.) regarding the program asused by the first processing resource, file system information (e.g.,directories, file names, file system functions, information types, etc.)regarding the program as used by the first processing resource, processmanagement information (e.g., scheduling information, process state,process attributes, process supervisory calls, etc.) regarding theprogram as used by the first processing resource, security information(e.g., keys, passwords, encryption algorithm, authentication,identification, etc.) regarding the program as used by the firstprocessing resource, and an instruction set type for the firstprocessing resource.

The method continues at step 158 where the security control module 46facilitates conversion of the first execution settings into secondexecution settings for the second processing resource. This may be in avariety of ways. For example, the security control module determines adifference between memory management function of the first processingresource and the second processing resource and converting, based on thememory management difference, memory management information regardingexecution of the program by the first processing resource into memorymanagement information regarding execution of the program by the secondprocessing resource. As another example, the security control moduledetermines a difference between file system management function of thefirst processing resource and the second processing resource andconverting, based on the file system management difference, file systeminformation regarding execution of the program by the first processingresource into file system information regarding execution of the programby the second processing resource.

As yet another example, the security control module determines adifference between process management function of the first processingresource and the second processing resource and converting, based on theprocess management difference, process management information regardingexecution of the program by the first processing resource into processmanagement information regarding execution of the program by the secondprocessing resource. As a further example, the security control moduledetermines a difference between security management function of thefirst processing resource and the second processing resource andconverting, based on the security management difference, securityinformation regarding execution of the program by the first processingresource into security information regarding execution of the program bythe second processing resource. As a still further example, the securitycontrol module determines an instruction set type of the secondprocessing resource and converting, based on the instruction set type ofthe second processing resource, operational instructions of the programinto machine language for a processor of the second processing resource.

The method continues at step 160 where the security control modulede-assigns the first processing resource from executing the program, orportion thereof, and assigns the second processing resource to executethe program, or portion thereof. In accordance with this method, thenext time the program, or portion thereof, is evoked, a differentcentral processing resource will execute the program, or portionthereof, such that execution of the program is changed, which changesinternal operation of the computing device thereby reducing adverseimpact of the malicious software.

FIG. 28 is a logic diagram of another example of a method of securing acomputing device 24 that begins at step 150 where the security controlmodule determines to change operation of a program, or portion thereof,of the computing device. Such a determination may be done in a varietyof ways as were discussed with reference to step 130 of FIG. 21. Thesecurity control module may determine to change the program, or portionthereof, change the central processing resource assigned to execute theprogram, or portion thereof, or changing both the program, or portionthereof, and the central processing resource executing the program, orportion thereof.

When both the program, or portion thereof, and the execution of theprogram, or portion thereof, are to be changed, the method continues atstep 172 where the security control module facilitates a change of theprogram, or portion thereof, to produce a changed program. The changingof a program may be done as previously discussed. The method continuesat step 154 where, as discussed with reference to FIG. 27, the securitycontrol module selects a second processing resource of the centralprocessing resources to execute the changed program.

The method continues at step 156, where, as discussed with reference toFIG. 27, the security control module ascertains first execution settingsof the program as currently used by a first processing resource s forexecuting the program.
